Abstract

Monoacylglycerols – thanks to their amphipathic properties – belong among non-ionogenic surfactants. Their additional unique properties, such as antistatic, microbicidal, and lubricating, are also well known. One possibility for preparing pure individual monoacylglycerols is the reaction of fatty acid with glycidol. In this paper, the catalysis of this reaction with some chromium(III) complexes is described. Compounds prepared in high yields were 1-monoacylglycerols of caprylic, capric, lauric, oleic, and palmitic acids, the purity of which was verified by high performance liquid chromatography.

Kurzfassung

Monoacylglycerole gehören aufgrund ihrer amphipathischen Eigenschaften zu den nichtionogenen Tensiden. Ihre antistatischen, mikrobiziden und schmierenden Eigenschaften sind ebenfalls gut bekannt. Eine Möglichkeit zur Darstellung von reinen individuellen Monoacylglycerolen ist die Reaktion von Fettsäure mit Glycidol. In der vorliegenden Arbeit wird die Katalyse dieser Reaktion mit einigen Chrom(III)-Komplexen beschrieben. So wurden in hoher Ausbeute 1-Monoacylglycerole der Capryl-, Caprin-, Laurin-, Öl- und Palmitinsäuren dargestellt. Der Reinheitsgrad dieser Verbindungen wurde mittels Hochdruckflüssigkeitschromatographie überprüft.
